Being the target of relentless, ubiquitous, and unjust persecution proves to the paranoid narcissist how important and feared he is. Being hounded by the mighty and the privileged validates his pivotal role in the scheme of things. Only vital, weighty, crucial, essential principals are thus bullied and intimidated, followed and harassed, stalked and intruded upon - goes his unconscious inner dialog. The narcissist consistently baits authority figures into punishing him and thus into upholding his delusional self-image as worthy of their attention. This provocative behaviour is called Projective Identification.
Paranoia is use by the narcissist to ward off or reverse intimacy. The narcissist is threatened by intimacy because it reduces him to ordinariness by exposing his weaknesses and shortcomings and by causing him to act "normally". The narcissist also dreads the encounter with his deep buried emotions - hurt, envy, anger, aggression - likely to be foisted on him in an intimate relationship.
The paranoid narrative legitimizes intimacy repelling behaviours such as keeping one's distance, secrecy, aloofness, reclusion, aggression, intrusion on privacy, lying, desultoriness, itinerancy, unpredictability, and idiosyncratic or eccentric reactions. Gradually, the narcissist succeeds to alienate and wear down all his friends, colleagues, well-wishers, and mates.
Even his closest, nearest, and dearest, his family - feel emotionally detached and "burnt out".
